Tmc “UB90” Unitised Bearing Trailer axles
UB90 axles feature the case carburised UNIPACTM bearing system from TIMKEN, which is pre-greased, pre-sealed and all pre-adjusted ex factory for minimum maintenance.
UB90 allows the operator to eliminate the human factor from seal maintenance and bearing adjustment, thus ensuring substantially lower life cycle costs.
Available with either drum or disc brakes and with 10 stud 285pcd or 335pcd hubs, TMC's UB90 unitised bearing axles incorporate the latest technology from TIMKEN and Wabco.
